Don't ask me. I am still trying to figure how all the glaciers that covered Indiana, Ohio, Michigan, Illinios and Wisconsin 20,000 years ago went. Seems there must have been a lot of global warming going on, but no sign of man.

They are all in a series of large holes in liquid form. Today we call them the great lakes. Of course some must have spilled into the ocean right over Niagra Falls.
Cute huh? :o)
